    • A preceding-vehicle follow-up control apparatus is arranged to calculate a target vehicle speed for following-up a preceding vehicle at a target vehicle-to-vehicle distance. The target vehicle speed is calculated from an equation having a form of a linear combination of a form which includes a linear connection between a product of a first gain and a difference between the vehicle-to-vehicle distance and the target vehicle-to-vehicle distance and a product of a second gain and the relative speed. The control apparatus controls a driving apparatus and a transmission apparatus of a vehicle so as to adjust a vehicle speed at the target vehicle speed. This enables the vehicle-to-vehicle distance to be converged into a target value without excessively increasing or decreasing the relative speed during this follow-up control.

    • In an up-conversion laser using Tm, blue light having a wavelength of 450 nm and blue light having a wavelength of 480 nm are outputted simultaneously. A high output is enabled with a high efficiency, and a green up-conversion laser is also realized by a similar means. A hybrid fiber laser apparatus includes a light source which outputs light near a wavelength A, and comprises a means for reflecting light near the wavelength A, which is provided at another end of the optical fiber, thereby to form an optical resonator for the wavelength A. In this hybrid fiber laser apparatus, an up-conversion fiber is provided in the optical resonator for the wavelength A, and optical resonator structures for a wavelength B constructed by reflection means and for a wavelength B are respectively provided at two positions at both ends of the up-conversion fiber. Of the two reflection means, the reflection means in the laser diode chip side is arranged so as to achieve high reflection, and the other reflection means in the other end side is arranged so as to achieve partial reflection, thereby to obtain output light having a wavelength B from the partial reflection side.
